1．________ (H)headmaster Smith is quite good at painting and it is said that he is ________ Picasso.
A．The; / B．/; a
C．/; / D．The; a
解析：选B 句意：史密斯校长很擅长绘画，据说他是又一位毕加索。本句中headmaster表示职位，其前不用冠词；第二空表示的是他被称为又一位毕加索，故使用不定冠词a，表示泛指。故选B项。
2．The good result ________ the correct methods, that is to say, correct methods ________ the good result.
A．results in; lie in B．results in; lie to
C．lies in; result in D．lies to; result in
解析：选C 句意：好的结果在于正确的方法，也就是说，正确的方法导致好的结果。lie in“在于”；result in“导致”。所以选C。
3．(2019·盐城模拟)We tend to ________ happiness with freedom, but, as a psychotherapist and writer has observed, without obstacles to our desires it's harder to know what we want, or where we're heading.
A．combine B．compare
C．equip D．equate
解析：选D 句意：我们往往会将幸福和自由等同，但是正如一位心理治疗师兼作家所观察到的那样，如果欲望没有障碍，我们就不会知道自己想要什么，也不知道自己要去往何处。combine“结合”；compare“比较”；equip“装备”；equate“等同于”。根据句意可知选D。
